- Part I Create an interface for a Store application. Provide at least 3 function. Part II Create a type of Store class. Implement the methods introduced in the interface. Note: Do not compress your files, submit only java files. Note: Do not forget to justify your answers with comments.arrow_forwardWrite another Java class named Patient that contains: ■ A private integer data field called id. ■ A private static integer data field called numberOfPatients that counts the number of Patient objects created (default value 0). ■ A private String data field called name. ■ A private Address variable called address. ■ A private File variable called file that refers to a database.txt file. ■ A constructor that creates a patient object with specified name and address. Note that the id of patients is auto-incremented. If 3 patients are created the first one would have id 1, the second id would be 2 and the third id 3. ■ A static method getNumberOfPatients() that returns the number of patients. ■ A method getId() that returns the patient’s id. ■ A toString() method that returns a one-line description of the patient. ■ A savePatientToFile() method that is called every time a new patient object is created to save the patient information (patient object) to the database file.arrow_forwardAsk the user for three employees. Store the data into three employee object. Display those employees in a table. on this program make 2 files, one is Employees.java and the one has a Main. write in java and use test case 1 as an example.arrow_forward
- please use java to answer the following question Implement a program with a GUI and Action listener that looks like the one shown below You should connect to the database ( make sure you have maximum 5 rows in your table) The table should contain of the name, card number and the pin number of the customers who uses the ATM once you enter the card number and the pin number that exist in the database, then by clicking on the Login button, you could show a dialogue dialog box in which it shows the name of the customer and then indicates that that name is login successfully ( Mehrnaz is login successfully). Otherwise, the dialogue box indicates that the information does not exist in the database. The clear button will clear all the information on the GUI.arrow_forwardIn Java, create a program that asks the user for their first name, last name, address, city, zip, phone number, email, hourly rate, start date, end date, and number of hours worked. The program must consist of three classes, each one in its own file (I.e. Employee.java, PayPeriod.java) and called back to a main.java file. Classes named Employee, PayPeriod, and Payroll Manager. Employee gathers the info about the employee. PayPeriod gathers the payment info. PayrollManager computes and displays the info. PayrollManager should also use methods such as: double CalculateGrossPay(Employee, PayPeriod), double CalculateRegularPay(Employee, PayPeriod), double CalculateOvertimePay(Employee, PayPeriod), and void PrintPaystub(Employee, PayPeriod). output: ------------------------------------------Employee ID: 123456 Last Name: last First Name: first Hours Worked: 50 Hourly Rate: $10.00 Regular Pay: 40 hours at $10/hr: $400.00 Overtime Pay: 10 hours at $15/hr: $150.00 Gross…arrow_forwardCreate a C# program named ConferencesDemo for a hotel that hosts business conferences. Allows a user to enter data about five Conference objects and then displays them in order of attendance from smallest to largest. The Conference class contains fields for the following: group - The group name (as a string) date - The starting date (as a string) attendees - The number of attendees (as an int) Include properties for each field. Also, include an IComparable.CompareTo() method so that Conference objects can be sorted in order from least to greatest attendees. Your output for each conference should match the following: NAME Conference starts on DATE and has ATTENDEES attendees using System; using static System.Console; class ConferencesDemo { static void Main() { // Write your main here } }arrow_forward
- Design a program using a console application in java, named studentMarksReport that will print the final result obtained by a student with the weighting of each module. Make use of a class named Student that contains variables to store the student number, test result, assignment result and exam. Create a constructor that accepts the student number, test result, assignment result and the exam result as parameters and create get methods for the variables (Use Scanner to get variable from the user). Create a subclass called Student_Report that extends the Student class. The Student_Report overrides all getter methods and the constructor from Students. Write code for the print_report method which calculates each assessment weighting as follows: Assessment Weighting Test 25% Assignment 25% Exam 50%arrow_forwardA library wants to manage its collection of books and authors more efficiently. They would like to create a Python program to help with this task. The following requirements need to be implemented: Create an Author class with the attributes: name, dob (date of birth), and nationality. The class should have a __str__ method to represent the author in a user-friendly format. Create a Book class with the following attributes: title, author (an instance of the Author class), publication_date, and price. Also, include a class variable all_books that keeps a list of all book instances created.The Book class should have: A __str__ method to represent the book in a user-friendly format. A __eq__ method to compare two books. Two books are considered the same if they have the same title and author. A __lt__ method to compare two books based on their publication dates. A class method get_all_books that returns a list of all books in the library. A static method most_expensive_book that takes…arrow_forwardProblem Description and Given Info For this assignment you are given the following Java source code files: IStack.java (This file is complete – make no changes to this file) MyStack.java (You must complete this file) Main.java (You may use this file to write code to test your MyStack) You must complete the public class named MyStack.java with fields and methods as defined below. Your MyStack.java will implement the IStack interface that is provided in the IStack.java file. You must implement your MyStack class as either a linked list or an array list (refer to your MyArrayList and MyLinkedList work). Your MyStack must not be arbitrarily limited to any fixed size at run-time. UML UML CLass Diagram: MyStack Structure of the Fields While there are no required fields for your MyStack class, you will need to decide what fields to implement. This decision will be largely based on your choice to implement this MyStack as either an array list or a linked list. Structure of the Methods As…arrow_forward
